NVIDIA T550 Mobile vs NVIDIA T600 Mobile Comparison

The NVIDIA T550 Mobile and NVIDIA T600 Mobile are two professional mobile GPUs built on the same TU117 chip and Turing architecture, yet they are configured with distinct trade-offs. The data shows the T550 Mobile holds a narrow but consistent lead in both recorded benchmarks, with an average benchmark score of 33161 compared to 32849 for the T600 Mobile, a difference of about 1%. The T550 achieves this through significantly higher clock speeds (1065 MHz base and 1665 MHz boost versus 780 MHz base and 1410 MHz boost) and a wider shading unit count (1024 vs 896), while the T600 counters with a larger 128-bit memory bus that doubles bandwidth to 192.0 GB/s. Given the measured results, the T550 Mobile is the stronger choice for raw compute performance in OpenCL and Vulkan workloads, while the T600 Mobile’s advantage lies solely in memory throughput, though this does not translate into a benchmark win. For users prioritizing the highest available scores in the data, the T550 Mobile is the pick; for those needing more memory bandwidth for specific bandwidth-sensitive tasks, the T600 Mobile offers that capability, albeit at a higher 40 W TDP and lower overall compute output.

The Verdict

The benchmark results are unambiguous: the NVIDIA T550 Mobile outperforms the NVIDIA T600 Mobile in both recorded tests. In Geekbench OpenCL, the T550 scores 35521 versus 35486 for the T600, a marginal 0.1% edge. In Geekbench Vulkan, the T550 extends its lead to 2%, scoring 30801 against 30211. The average benchmark score reflects this overall trend, with the T550 at 33161 and the T600 at 32849, placing the T550 1% ahead. Both cards sit at the 77th percentile among all GPUs, indicating they occupy a similar performance tier, but the T550 is consistently the faster part.

The T550’s advantage stems from its higher clock configuration. Its 1665 MHz boost clock is 18% higher than the T600’s 1410 MHz boost, and its base clock of 1065 MHz is 37% higher. Combined with 1024 shading units versus 896, this yields a peak FP32 throughput of 3.410 TFLOPS for the T550, which is 35% above the T600’s 2.527 TFLOPS. The T550 also leads in texture rate (106.6 GTexel/s vs 78.96 GTexel/s) and pixel rate (53.28 GPixel/s vs 45.12 GPixel/s). The T600’s only specification advantage is its memory subsystem: it features a 128-bit bus and 192.0 GB/s bandwidth, double the T550’s 64-bit bus and 96.00 GB/s bandwidth. However, this memory advantage does not produce a benchmark win in the data.

For most tasks, the T550 Mobile is the superior choice. Its higher compute throughput and clock speeds deliver better results in the measured OpenCL and Vulkan workloads. The T600 Mobile is only preferable if the application is strictly limited by memory bandwidth, as its 192.0 GB/s throughput is exactly double the T550’s. That said, the benchmark data shows no scenario where the T600 wins, so the T550 is the recommended part for general professional use. The T550 also draws less power at 23 W versus 40 W for the T600, making it more efficient per frame or per compute operation. Both are end-of-life products, but the T550’s performance lead makes it the default pick.

Architecture Differences

Both the NVIDIA T550 Mobile and the NVIDIA T600 Mobile are built on the same fundamental architecture. They share the TU117 chip, which is manufactured on a 12 nm process at TSMC, with a die size of 200 mm² and 4,700 million transistors. This results in an identical transistor density of 23.5M per mm². Neither GPU features ray tracing cores or tensor cores, which is consistent with the Turing generation but indicates that these are compute-focused professional parts without dedicated hardware for those workloads. The architecture is classified as Quadro Turing-M (Tx000), and both have the same predecessor (Quadro Pascal-M) and successor (Ampere-MW). The API support is also identical: DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4.

The key architectural differences are in the execution resources and clock behavior. The T550 Mobile has 1024 shading units, 64 texture mapping units (TMUs), and 32 raster operation units (ROPs). The T600 Mobile has fewer shading units (896) and TMUs (56), but retains the same 32 ROPs. This means the T550 has 14% more shading units and 14% more TMUs than the T600. The clock speeds amplify this difference: the T550’s base clock is 1065 MHz and boost is 1665 MHz, while the T600’s base is much lower at 780 MHz and boost is 1410 MHz. The higher clocks on the T550 are likely a deliberate binning choice, allowing it to achieve higher throughput within a lower 23 W TDP, whereas the T600 has a higher 40 W TDP despite lower clock speeds. The memory architecture also differs fundamentally: the T550 uses a 64-bit bus, while the T600 uses a 128-bit bus, though both run the same GDDR6 memory at 1500 MHz with 12 Gbps effective speed.

Specification Differences

The specification sheet shows several divergences between the two GPUs, with the most impactful being clock speeds and memory configuration. The T550 Mobile operates at a base clock of 1065 MHz and a boost clock of 1665 MHz, whereas the T600 Mobile runs at a substantially lower 780 MHz base and 1410 MHz boost. This clock difference is the primary driver of the T550’s performance lead. In terms of compute resources, the T550 has 1024 shading units and 64 TMUs, compared to 896 shading units and 56 TMUs on the T600. Both have 32 ROPs. The resulting fill rates differ: the T550 achieves a pixel rate of 53.28 GPixel/s and a texture rate of 106.6 GTexel/s, while the T600 achieves 45.12 GPixel/s and 78.96 GTexel/s respectively. FP32 throughput is 3.410 TFLOPS for the T550 and 2.527 TFLOPS for the T600; FP16 is similarly scaled at 6.820 TFLOPS and 5.053 TFLOPS, both with a 2:1 ratio.

Memory is where the T600 counterbalances its compute deficit. Both have 4 GB of GDDR6, but the T600’s bus width is 128-bit versus 64-bit on the T550. This yields a memory bandwidth of 192.0 GB/s for the T600, exactly double the T550’s 96.00 GB/s. The memory clock is the same at 1500 MHz with 12 Gbps effective speed. Power consumption also differs significantly: the T550 is rated at 23 W, while the T600 is rated at 40 W, making the T550 markedly more power-efficient. Both use PCIe 3.0 x16 and have no power connectors, with display outputs described as portable device dependent. The T600 has a recorded release date of April 11, 2021, while the T550 has no recorded release date. Both are end-of-life products.

Head-to-Head Benchmarks

The head-to-head data shows the T550 Mobile winning both recorded tests, though the margin varies. In the Geekbench OpenCL test, the T550 scores 35521, edging out the T600’s 35486 by just 0.1%. This is a near-tie, indicating that the T600’s doubled memory bandwidth helps close the gap in OpenCL workloads that might be memory-sensitive. However, the T550 still wins, likely due to its higher compute throughput. The Geekbench Vulkan test shows a clearer separation: the T550 scores 30801, which is 2% higher than the T600’s 30211. This suggests that Vulkan workloads benefit more from the T550’s higher clock speeds and additional shading units, outweighing the T600’s memory bandwidth advantage.

Looking at the nearest rivals for context, the T550 Mobile’s average score of 33161 places it just 0.5% above the NVIDIA P104-100 (32982) and 0.1% below the AMD Radeon Pro 570 (33207). The T600 Mobile’s average score of 32849 puts it 0.4% behind the same P104-100 and 0.8% ahead of the AMD Radeon RX 590 GME (32601). Neither GPU is a clear outlier in its performance tier, but the T550 consistently ranks above the T600. The T550’s win count is 2 out of 2 tests, while the T600 has zero wins. This is a decisive outcome: despite the T600’s superior memory bandwidth, the T550’s compute advantages translate directly into better benchmark results. The data does not show any test where the T600 Mobile outperforms the T550 Mobile, making the T550 the definitive choice for users who prioritize measured performance.
